IMPROVEMENTIIN WATER-HEATER?, Fon STEAM FIRE-ENGINE BolLERs.

Speccation forming part of Letters Patent No. 32,026, dated October 8, 1872.

To all lwhom it' may concern:

Be it known that I, EDWARD A. RUSSELL, of Milwaukee, in the county of M ilwaukee, in the State of Wisconsin, have invented certain Improvements in Waterdeater for Fire-En gilles, of which the following is a specification:

Nature cmd Object of the Intent/ion.

Description of the Drawing fcrllzf'ing part of this Specification.

Figure l is a vertical sectional view of my invention attached to the boiler ot' a steam lire-engine.

General Description.

A is the outside shell of the heater; B, the inside shell, forming a reservoir for, water; C, tlle tire-chamber; D, the bottom ofthe ashpit 5 D', the grate; E, pipe which leads from the boiler to the bottom ofthe heater leading into the water-space, F, pipe leading from the m top of the water-space in the heater to the upper part of the boiler 5 H, check-valve in pipe E, opening to the heater, but closed to the boiler, so that water can pass from the boiler to the heater, but not from the heater to the boiler; I, cock in the pipe E; K, cock in the upper pipe F; M, smokepipe; N, rear end of the boiler to the engine 5 O, platform or coalreservoir, on which theheater stands; P, a

'shell on the outside of the upper part of the heater. This shell is made larger than the heater, so that there is an open-space between it and the heater for the lire and smoke to pass, and the bottoni and top of this shell are riveted onto the shell of the heater. Q are illles passing fromthe nre-chamber through the water-space to the inside of this outside shell P, and also passing into the space above the water-reservoir. It, a damper at the top of the fire-chamber; S,handle and shaft tothis damper R. When this damper is closed the fire and smoke will pass out through the lower ues Q.

and in again through the upper openingsQ above the damper. This heater stands all the time on platform O, connected with the boiler, and when the cocks I and K are open, if the boiler has water ill it, the water-reservoir in the heater will be iilled; and to feed fuel into this heater just remove the smoke-pipe M and put the fuel in and it will fall onto the grate. T, door to the ash-pit, allowing the admission of air. As the water is heated inthe reservoir of the heater it will be forced through the upper pipe F to the boiler, and the lower pipe E will supply the water again, and so the water will circulate from the boiler to the heater and from the heater to the boiler again, and

keep the water in the boiler at the boiling-point alld wllen there is an alarm of re there is nothing to do with the heater but to let it stand and take it along with the engine. The pipe M being left hanging, all the preparation there is to the engine and heater is to close cock L and play away. In this case it is not necessary to start a tire under the boiler until you get your engine set where you want to use it at the tire. The stealn can be got up high ellough to work by the time you can get the pipes in position.
